Skin Renewal Booster is a very expensive, effective, yet ultimately problematic AHA exfoliant. The amount of lactic acid is likely above 5% and that fact coupled with this product’s pH of 3.6 ensures exfoliation will occur.
Beyond the AHA, this contains a tiny amount of salicylic acid (BHA) but likely not enough for your skin to notice a difference. Skin Renewal Booster is problematic because it contains drying, irritating sulfur plus some fragrant plant extracts known to cause irritation. Combined, they can potentially make oily skin worse by stimulating excess oil production at the base of the pores, not to mention that fragrant plant extracts also stand a good chance of worsening redness. There are many AHA exfoliants that work without excess irritation (and cost less, too).
A hydroxy acid concentrate of smoothing Lactic Acid, Salicylic Acid and Hibiscus Extract stimulates cell renewal, exfoliates dead skin cells and improves skin texture. Vitamins A and C help reverse signs of photo-aging while smoothing skin. Contains no artificial fragrance or color.

Dermalogica's name implies a logical relationship to dermatology, which makes it sound as if you are getting serious skin care. The subtitle on their products is even more commanding: "A Skin Care System Researched and Developed by the International Dermal Institute." But what is the International Dermal Institute, you ask? Are there any dermatologists there? Apparently not: The International Dermal Institute is a Dermalogica-owned school for aestheticians who want an education beyond what is required for their cosmetology license, and the classes are taught by aestheticians.
Does the professional atmosphere of the school associated with Dermalogica mean better products? The proof is in the pudding, and this pudding is, for the most part, just Jell-O, not chocolate mousse. A company so concerned with skin-care education should be ashamed of itself for offering so many products that damage skin with known irritants and, more egregiously, offering so many sunscreens that lack sufficient UVA-protecting ingredients. Dermalogica's education-oriented, serious-minded, and clinical positioning doesn’t mesh with the majority of their products, and is on par with tobacco company executives teaching an aerobics class.
According to company history, the reason Dermalogica products came to be was that founder Jane Wurwand could not find a spa-oriented skin-care line that met her criteria. She was dismayed that so many skin-care lines aimed at the aesthetics market had products that contained alcohol, artificial colors, fragrance, mineral oil, and lanolin, ingredients that she believed had a well-documented history of problems. That's true for fragrance and alcohol (and artificial colors to a lesser extent), but mineral oil and lanolin have no documented history of causing skin problems. If anything, quite the opposite is true. Further, if Dermalogica's founders were so concerned about potentially or definitively harmful ingredients, why do their products contain so many of them? Where is the research proving that lavender oil, camphor, balm mint, arnica, ginger oil, and citrus oils are helpful for skin?
